O que são Core Web Vitals?
Core Web Vitals are three user-experience metrics used by Google as a ranking signal: LCP measures loading speed, INP measures responsiveness and CLS measures visual stability. INP replaced FID in 2024. Together, these metrics feed the Page Experience report.
Core Web Vitals afetam diretamente o ranking no Google?
Yes, but they usually act as a tiebreaker between pages with similar content relevance rather than as a dominant factor. Highly relevant pages can still rank with poor Core Web Vitals. Their strongest practical effect is indirect: a better experience can reduce abandonment, increase engagement and improve conversions.
Como o Google mede Core Web Vitals para ranking?
O Google usa dados do CrUX (Chrome User Experience Report), coletados de usuários reais do Chrome com opt-in. O critério é que ao menos 75% das sessões de uma URL (ou do domínio, se sem dados suficientes) tenham métricas no estado "Good". Sites com pouco tráfego orgânico têm threshold medido a nível de domínio/origem.
What is the difference between lab and field CWV optimization?
Lab data comes from Lighthouse running under simulated CPU and network conditions, which is useful during development. Field data comes from CrUX and reflects real visits over the previous 28 days, segmented by device and connection type. Google evaluates field data for Core Web Vitals, and improvements can take up to 28 days to appear.
É possível ter 100/100 no PageSpeed e CWV ruins no campo?
Yes. PageSpeed Insights uses Lighthouse lab data for its 0 to 100 score, while Core Web Vitals rely on field data. A site can score 100 in a simulated desktop test and still have poor field LCP because visitors use slower connections, load uncached images or trigger heavy JavaScript during interaction.
Frequently asked questions
Answers before the first call.
What's the difference between assessment and optimization? +
Assessment diagnoses. Optimization executes. First we measure, then we optimize until green.
Do you guarantee CWV in the green? +
Yes. We guarantee LCP, CLS and INP within Google’s “good” thresholds.
Does Optimization impact ranking? +
Directly. Core Web Vitals have been a confirmed ranking factor by Google since 2021.

(04) Our delivery standard
What you can hold us to.
An agreed deadline is a kept deadline. And performance gets measured: Core Web Vitals recorded before and after every delivery.
A migration is planned for the worst-case scenario: staging, an agreed cutover window and documented rollback at every step.
No project reaches production without Daniel Paz's technical review. No exceptions, small projects included.
